What sealant or caulk to use ?

[NanciL]

I have a leak in the connection between my fresh water inlet and the inside pipe and need to take the outside flange/connection fitting off to get to it.
What is the proper sealant or caulk to use when I reinstall it?

Please don't answer unless you have done it or are an RV tech who does it a lot

Butyl or putty tape. For extra credit you can drape a bead of ProFlex RV caulk over the top half of the fitting flange. That is what I do.

Good luck with the fill tube. I hate those, they always leak at the ends where clamped. It's a poor design. Seems like I say that a lot about RV stuff. 🙂

I replaced several items on my last trailer and used butyl tape to reseal them all as that was used by the manufacturer.

Thank you,

I'll see if I can get some

Correct .... normally caulk/sealants are only used as a secondary seal. While there might be others two other specific adhesive/sealants made for bedding fixtures are the 3M Marine 4000 and 5000 series Marine products which are my choices to use as a secondary caulk/sealant in addition to the normal butyl tape.

A final option to use in stead of butyl tape would be the double sided Eternabond tape.

I'd use a Geocel polymer sealant. They endure UV and weather greater than any other sealant I've used.
